摘　　要：为了探索氨基寡糖素对番茄的生长调节及对线虫的防效,本文研究了不同浓度氨基寡糖素对番茄的影响。结果表明,与清水对照相比,冲施氨基寡糖素5.0‰水剂,番茄线虫数量减少63.59%、线虫相对防效为52.81%、叶绿素含量(SPAD值)增加35.97%、株高增加8.05%、茎粗增加4.01%。In order to explore the effect of amino-oligosaccharide on tomato growth regulation and control against nematodes,this paper studied the effect of different concentrations of amino-oligosaccharide on tomato.The results showed that compared with the water control,when tomato flushed with amino-oligosaccharide 5.0‰water agent,the number of tomato nematodes decreased by 63.59%,the relative control effect was 52.81%,the chlorophyll content(SPAD value)increased by 35.97%,plant height increased by 8.05%and stem diameter increased by 4.01%.
